71278003 ÷ 449 
The aim is to understand the frequency of 449 in 71278003.

Advancing to step 1:
The number 449 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 449

Step 2:
449 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 449

Moving on to step 3:
When dividing 712 by 449, we get 1 with a remainder of 263.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 449 from 712, we get 263.
Take the next digit (7) from the dividend and append it to 263, then repeat: 2637 / 449

Moving on to step 4:
449 can be fit into 2637 5 times, resulting in a remainder of 392.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2245 from 2637 leaves us with 392.
Include the next digit (8) from the dividend after 392, then repeat: 3928 / 449

Moving on to step 5:
449 can be fit into 3928 8 times, resulting in a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we take 3592 away from 3928, we end up with 336.
Grab the next digit (0) from the dividend, add it to 336, then carry on: 3360 / 449

Step 6:
449 can be fit into 3360 7 times, resulting in a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 1587.0
The remainder is 217 after subtracting 3143 from 3360.
Bring next digit (0) of the dividend behind the 217 and repeat the process: 2170 / 449

Going ahead to step 7:
2170 divided by 449 is 4 with a remainder of 374.
Record the quotient 4 as the next digit in the result. 
Result so far: 15874.0
Subtracting 1796 from 2170 leaves us with 374.
Grab the next digit (3) from the dividend, add it to 374, then carry on: 3743 / 449

Advancing to step 8:
3743 divided by 449 is 8 with a remainder of 151.
The number 8 becomes the next digit in our result. 
Result so far: 158748.0
If we take 3592 away from 3743, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 9:
When dividing 1510 by 449, we get 3 with a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 158748.3
Subtract 1347 from 1510 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 10:
1630 divided by 449 is 3 with a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 158748.33
Deduct 1347 from 1630 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The quotient of the division is 158748.33, and the remainder is 0.283.
